(CNN)Manchester City became the first men's team in history to win the English domestic treble, beating Watford 6-0 in the FA Cup final at Wembley. First half goals from David Silva and Gabriel Jesus -- although there was some debate as to whether Raheem Sterling got the final touch -- gave City a deserved lead at the break, though it wasn't all plain sailing. City got a fourth soon after through Jesus and now had more history in its sights.
